console multi-line parsing

[jessdtate]

this probably relates to the fixes from #1530. When trying to execute an if statement or a for loop in the python console, the lines the context is removed, making it impossible to run these type of functions. This affects the top-level functionality in IWP and I think the triggered events.

@jessdtate I'll need some examples posted--my python bug memory space is only like 24Kb

[jessdtate]

this can be as simple as:

for k in range(5):
  print(k)

Trying to run code like this in the console window or top-level tab of interfacewithpython will exit out of the loop after the for k in range(5): line, so it is impossible to do significant loop or if statement.

The one I wanted to use in the IWP top level tab, but could not, is

if not 'eng' in vars():
  eng = matlab.engine.start_matlab() #could be any assignment
