Error Stack Implementation

This is an incredibly simple implementation of a very complex error handling facility. It contains the ability to track multiple errors from multiple packages simultaneously. In addition, it can track errors of many levels, save data along with the error, context information such as the exact file, line number, class and function that generated the error, and if necessary, it can raise a traditional PEAR_Error. It has built-in support for PEAR::Log, to log errors as they occur

Since version 0.2alpha, it is also possible to selectively ignore errors, through the use of an error callback, see pushCallback()

Since version 0.3alpha, it is possible to specify the exception class returned from push()

Since version PEAR1.3.2, ErrorStack no longer instantiates an exception class. This can still be done quite handily in an error callback or by manipulating the returned array
