1.0.1

• Fixed a major bug where Python int and float types were handled with 32-bit instead of 64-bit precision. This caused certain int values to be rejected and other float values to be rounded incorrectly. Closes #13.
• As a matter of convenience, the Buffer.row method can now take None column values. This has the same semantics as skipping the column altogether. Closes #3.
• Fixed a minor bug where an auto-flush error caused a second clean-up error. Closes #4.
