/**
* Clean, simple class for sending HTTP requests
* in PHP.
*
* There is an emphasis of readability without loosing concise
* syntax. As such, you will notice that the library lends
* itself very nicely to "chaining". You will see several "alias"
* methods: more readable method definitions that wrap
* their more concise counterparts. You will also notice
* no public constructor. This two adds to the readability
* and "chainabilty" of the library.
