Backtrace

PHP Backtrace utils

is this really necessary?

• There are two functions to get a backtrace in PHP. debug_backtrace and xdebug_get_function_stack... To get the trace for a fatal errpr. xdebug_get_function_stack must be used. This utility uses xdebug when necessary and normalizes the results.
• Ability to define classes/namespaces to skip over... Useful for when your framework wants to display a trace to the user... without all the internals that got to the point of generating the trace
• Utility for getting the surrounding file lines for each frame.
• getCallerInfo() utility method to get the calling file/line/function
