Regarding the output of "tao.var_v1_array" and "tao.var" interface commands #55

The output of tao.var_v1_array(var_name) is a huge list of all the values which requires additional parsing on the user end. A dictionary is preferred.

The output of tao.var(var_name) is a list of some (index?) values which does not include the variable value. Is this intended?

My example code below requires $LCLS_LATTICE, but I'm sure the same thing happens with other lattices with pre-defined variables.

`from pytao import Tao

tao = Tao(f'-init $LCLS_LATTICE/bmad/models/sc_hxr/tao.init -noplot')

tao.var_v1_array('q.L1')

tao.var('q.L1[1]')`

meas_value is the value of the variable and is outputted. The var_v1_array command was constructed to be used for gui display so that is why it is a list. Is there any issue to be resolved here?

56 adds special parsing of tao.var_v1_array

I assume this issue is solved and will close it.
