clawbot 62f769ae9b add SHA256File for checksumming a file 
SHA256File returns the SHA-256 digest of a file's contents as lowercase
hexadecimal, copying the file through the hash in chunks so its size does not
matter. Comes with a doc comment and table-driven tests. (closes #19)

clawbot 9708301eba add AtomicWriteFile for replacing a file in one step 
AtomicWriteFile writes to a temporary file in the same directory, flushes it,
sets the mode and renames it over the target, so a reader never sees a
half-written file and a failure leaves the old one untouched. Comes with a doc
comment and table-driven tests. (closes #17)

clawbot 9d3d35b3d7 add FileExists and DirExists for checking what is at a path 
FileExists reports whether a path holds a regular file and DirExists whether it
holds a directory, both answering false for anything they cannot look at.
Comes with doc comments and table-driven tests. (closes #15)
