+/**
+ * @file taos_monitor.h
+ * @brief Include taos_monitor.h to include the entire public API
+ * @mainpage Welcome to the documentation site for prometheus-client-c!
+ * @tableofcontents
+ * @section Introduction
+ *
+ * prometheus-client-c is a small suite of Prometheus client libraries targeted for the C programming language.
+ * In this brief tutorial you will learn how to create and register metrics, update metric samples, and expose metrics
+ * over HTTP.
+ *
+ * @section Creating-and-Registering-Metrics Creating and Registering Metrics
+ *
+ * prometheus-client-c supports the following metric types:
+ *
+ * * [Counter](https://prometheus.io/docs/concepts/metric_types/#counter)
+ * * [Gauge](https://prometheus.io/docs/concepts/metric_types/#gauge)
+ * * [Histogram](https://prometheus.io/docs/concepts/metric_types/#histogram)
+ *
+ * To get started using one of the metric types, declare the metric at file scope. For example:
+ *
+ * @code{.c}
+ *
+ * #incldue "taos_monitor.h"
+ *
+ * taos_counter_t *my_counter;
+ *
+ * @endcode
+ *
+ * Next, create a metric initialization function. You can create the metric and register it with the default metric
+ * collector registry in one chain of functions. A metric collector is responsible for collecting metrics and returning
+ * them. A metric collector registry is declared in global scope and contains metric collectors. More on this later...
+ *
+ * To create a metric and register it with the default metric collector registry in one shot, you may chain the metric
+ * constructor into the taos_collector_registry_must_register_metric function. For example:
+ *
+ * @code{.c}
+ *
+ * void foo_metric_init(void) {
+ *   my_counter = taos_collector_registry_must_register_metric(taos_counter_new("my_counter", "counts things", 0, NULL));
+ * }
+ *
+ * @endcode
+ *
+ * The first argument to taos_counter_new is the counter name. The second argument is the counter description. The third
+ * argument is the number of metric labels. In this case, we will only have one metric sample for this metric so we pass
+ * 0 to specify that no labels will be used. The 4th argument is an array of strings storing the metric labels. Since we
+ * have none, we pass NULL. A call to foo_metric_init within the program's main function will initialize the metrics
+ * for the file we just created to the default prometheus metric collector registery called
+ * TAOS_COLLECTOR_REGISTRY_DEFAULT
+ *
+ * @section Updating-Metric-Sample-Values Updating Metric Sample Values
+ *
+ * Now that we have a metric configured for creation and registration, we can update our metric within any of the
+ * functions of the file in which it was declared. For example:
+ *
+ * @code{.c}
+ *
+ * void my_lib_do_something(void) {
+ *   printf("I did a really important thing!\n");
+ *   taos_counter_inc(my_counter, NULL);
+ * }
+ * @endcode
+ *
+ * This function will increment the default metric sample for my_counter. Since we are not using metric labels, we pass
+ * NULL as the second argument.
+ *
+ * @section Program-Initialization Program Initialization
+ *
+ * At the start of the program's main function you need to do two things:
+ *
+ * * Initialize the default metric collector registry:
+ *
+ * @code{.c}
+ *
+ * taos_collector_registry_default_init();
+ *
+ * @endcode
+ *
+ * * For each file containing prometheus metrics, call its corresponding metric initialization function
+ *
+ * @code{.c}
+ *
+ * foo_metric_init()
+ *
+ * @endcode
+ *
+ * After initialization is complete, you may proceed to do work and update your metrics.
+ *
+ * @section Metric-Exposition-Over-HTTP Metric Exposition Over HTTP
+ *
+ * @todo Describe how to use libpromhttp to expose metrics over HTTP
+ *
+ * @section Where-To-Go-From-Here Where to Go From Here?
+ *
+ * Take a look at the [Files](https://github.internal.digitalocean.com/pages/timeseries/prometheus-client-c/files.html)
+ * tab in this documentation site for more information about the public API available to you. Also, you can take a look
+ * at the examples directory at the
+ * [Github repository](https://github.internal.digitalocean.com/timeseries/prometheus-client-c) for inspiration.

+ * @brief API PRIVATE hash function that returns an array index from the given key and taos_map.
+ *
+ * The algorithm is based off of Horner's method. In a simpler version, you set the return value to 0. Next, for each
+ * character in the string, you add the integer value of the current character to the product of the prime number and
+ * the current return value, set the result to the return value, then finally return the return value.
+ *
+ * In this version of the algorithm, we attempt to achieve a probabily of key to index conversion collisions to
+ * 1/M (with M being the max_size of the map). This optimizes dispersion and consequently, evens out the performance
+ * for gets and sets for each item. Instead of using a fixed prime number, we generate a coefficient for each iteration
+ * through the loop.
+ *
