Proposal for the new term in Plant Structure Ont: middle layer

[Pankaj Jaiswal]

Here is my suggestion. As of now this is the only instance of "middle 
layer' in the ontology. Therefore, we can have the term named  'middle 
layer' with a clear definition that this is the one found in anthers. 
Obviously the parent will be anther term. At a later time where there is 
another instance we can consider revising the name to 'anther wall: 
middle layer'. Yes having a colon is fine in the term name.
