/**
* Command to enable or disable a specific breakpoint.
*
* There are three possible ways this command can be executed:
* - If only a project is supplied, then only the breakpoints in that project
* will be enabled/disabled.
* - If a file path is supplied, then only the breakpoints for that file will be
* enabled/disabled.
* - If both a file name and a line number is supplied, then that specific
* breakpoint will be toggled.
* - If no breakpoint exists it will be created.
* - If the 'delete' option is supplied the breakpoint will be delete in the
* case where it would have been otherwise disabled.
*
* When toggling more than one breakpoint, the behavior is:
* - if all breakpoints are disabled, enable them all
* - if any breakpoints are enabled, disable them all
