Before, the tar operation would write the incorrect number of bytes to
indicate the end of the tar file. It should have been 2 blocks of 512
ascii zeros, but it would write 529 zeros instead.
The new implementation of `writeEndBlocks` is nicer and we can reuse
code with the `addEmptyBlock` function.
+ Added skeleton "Tar" operation with no functionality
+ Added intial functionality of "Untar"
+ Added a function in `Utils` `HTMLFormat` to generalize HTML generation
of files and folders (could later be used in Unzip).
I had a brief search for a small library for tar and untar operations,
however they were mostly for node (if anyone finds one we can drop in
that would be appreciated) or unmaintained. Luckily the tar spec is
relatively easy to understand just from Wikipedia.
Added "To Morse Code" and "From More Code" functions under the category
"Encryption / Encoding".
"To Morse Code" accepts 3 arguments:
1. Format options: e.g. ./- or Dot/Dash
2. Letter delimiter e.g. <space> or <newline>
3. Word delimiter e.g. <newline>
"From Morse Code" accepts 2 arguments:
1. Letter delimiter
2. Word delimiter
These operations are useful for taking the contents of a string, and making it
suitable for use as a stand alone string. For example, in an IDE you might see
a string which is represented as: "Say \"Hello\"". The escaped double quotes
are shown to make it clear that they do not end the string, despite the fact
that they are not truly part of the string. In order to get the raw string, you
would need to copy this, then manually remove the backslashes. The new
String_.run_unescape operation does this automatically.
The String_.run_escape is the inverse. It allows you to take a string like the
one above, and paste it between two quotes without having to manually escape
it.
