 * Command to remove breakpoints.
 *

 * - If only a project is supplied, then only the breakpoints in that project
 *   will be removed.
 * - If a file path is supplied, then only the breakpoints for that file will be
 *   removed.
 * - If both a file name and a line number is supplied, then that specific
 *   breakpoint will be removed.
