@Stack, Update the patch file with following changes.
# add test cases for both get and scan.
# add usage examples in scan/get helper.
Here is the usage info for this feature. Anything improper, please let me know.
thanks.

Besides the default 'toStringBinary' format, scan also supports customized
output format for each column.
User can define a CONVERTER, which follows the general column spec of
"cf:qualifier", like "cf:qualifier[:CONVERTER]".
The CONVERTER can be formatted as
1. either "converterFun" alone (e.g, toInt, toString)
2. or a complete pattern of 'c(MyConverterClass).converterFun'.
While using the 1st. CONVERTER definition, it chooses
"org.apache.hadoop.hbase.util.Bytes" as the default class.
Example:
hbase> scan 't1', {COLUMNS => ['cf:qualifier:toInt',
'cf:qualifier:c(org.apache.hadoop.hbase.util.Bytes).toInt'] }
ATTENTION!The above feature cannot be applied on the entire column family,
since it is too confusing to distinguish "cf:qualifier" and "cf:CONVERTER"
