    Description

      Frame left indexing with different column schemas of lhs and rhs currently fails as follows

      Caused by: java.lang.ClassCastException: org.apache.sysml.runtime.matrix.data.FrameBlock$DoubleArray cannot be cast to org.apache.sysml.runtime.matrix.data.FrameBlock$StringArray
      	at org.apache.sysml.runtime.matrix.data.FrameBlock$StringArray.set(FrameBlock.java:1209)
      	at org.apache.sysml.runtime.matrix.data.FrameBlock$StringArray.set(FrameBlock.java:1206)
      	at org.apache.sysml.runtime.matrix.data.FrameBlock.leftIndexingOperations(FrameBlock.java:760)
      

      We should provide a fast path for common schemas (based on memcopy as done so far) and a general path which requires object conversions.
