new term request: secondary parietal cell layer

[katica at acoma.stanford.edu]

This would be more appropriate term for developmental stages ontology, 
under 'anther development'. There is a term 'B formation of primary 
parietal and sporogenous cells', perhaps all we need is to add another 
term, 'formation of secondary parietal cells'.

Neither parietal cells or sporogenous cell form layers, they appear as 
a few distinct cells within four corners of anther primordia, with cell 
lineages that will give rise to particular layers of the anther wall.

They are certainly not cell types, and it would be wrong to add them as 
children under cell type node.
