> Support additional logical operators OR, NOT along with currently supported AND.
> Update the PXF ORC Accessor to support these opearators as well.
> Currently PXF only receives filters as a list of AND expressions. In anticipation of HAWQ-1048, PXF needs to support parsing a filter string that includes AND, OR, and NOT operators. The proposal for doing so is to introduce a special character 'l' for logical operators. With the following operations
> AND='0'
> OR='1'
> NOT='2'
> Thus the filter string
> 'a1c2o0a2c5o2l1' would translate to Column 1 < 1 OR Column 2 > 5
