Added Lyra_flareandgoes3.pro which is Ingolf's code for making nice
plots of LYRA data.

Created data directory and entered the 4 time line annotation files relevant to LYRA.
Wrote first draft of a function, extract_combined_lytaf(), which takes the
4 LYRA-relevant timeline annotation files and combines them in a python
variable.
Adjusted docstring of fin_lyra_events()
