Feature/add get values

[raeldor]

Created rudimentary get_values() function where you can pass in a list of data point keys and get back a list of values. This way you don't have to make multiple trips.

Can you update this to use MDXpy for MDX generation? We should avoid manual mdx generation going forward as it can make future compatibility hard to manage. MDXpy provides a good layer of abstraction.

Can you add the required tests for the new methods?

Thanks for the contribution @raeldor

I agree with @rclapp. Let's use mdxpy where we can. There might be some changes to MDX necessary with the upcoming TM1 v12 release. If we externalize the MDX construction to mdxpy that makes our lives easier.

Please add a test case similar to this one:

tm1py/Tests/CellService_test.py

Line 4159 in 29eb9ee

def test_get_value(self):

Can someone with more better Python skills than me code this using MDXpy? I'm not familiar with it, and not sure when I will get time to round back on this. Thanks.
