refactoring upsert so we can choose to encode differently for keys and values
Added comments and TODOs to PTable
Cloned newKey -> generateKey so that I can refactor it.
Inlined another setValues method call.
Rough refactor to extract kv values from expressions instead of from byte arrays.
Replace the rowkey generation with new key format.
- didn't fix any tests.

Failed tests:

Wire in HDataTypes for Binary, varBinary, varChar and orderedrawint32 for integer.
nits and notes.
By inspection WhileOptimizerTest.testStartKeyEndKey generates proper row keys.
- many broken unit tests, now to fix them.
fix for OrderedRawInt32 getsize.
javadoc RowKeySchema iterator methods
Drop dead code from RowKeySchema
row key schema comments and notes.
Fixed off by one error in KStruct
Added javastyle iterator for newstyle rowkeys.
Added Long and Byte new rowkey handlers
Modified RowKeySchemaTest to encode and decode using new style.
Added @Ignore for tests that fail because we don't handle CHAR(1) type yet.
Rowkey schema is cleared for now.
