'''Simple tool for finding tasks in tasks.json which match search terms.

Example usage:

Find tasks with dimension "os:Mac-14.5"
$ find_tasks.py ^os:Mac-14.5$

Find tasks with "ANGLE" in dimensions or name:
$ find_tasks.py ANGLE

Find tasks with dimension "os:Mac-14.5" and "ANGLE" in dimensions or name:
$ find_tasks.py ^os:Mac-14.5$ ANGLE
