Added an example of hypergeometric L-function

This will only work for 
http://127.0.0.1:37777/L/Motives/Hypergeometric/Q/A2.2.2.2_B1.1.1.1_t1.2/
and
http://127.0.0.1:37777/Motives/Hypergeometric/Q/A2.2.2.2_B1.1.1.1/t1.2
The database needs to be expanded for the other motives.

It touches things near John Jones' code.
