Takes a list in the format used internally in tcl programs for tagged data and writes it as a tagged file.
Takes a list in tagged format, and a list of conditions, and returns a new list in tagged format which contains those tag records which match the conditions.
The tests is a list of test items, each of which is a list of the form { labelname condition matchvalue }
The conditions are
tag readfile reads the whole file into memory before turning it into a list. Should be more memory efficient.
The -earlier and -later comparisons require TCL8.3
