Build the query tool

[blagae]

Design and write a tool that can be used to run specific analyses on subsets of the verse corpus.
Users must be able to:

• define which analysis they want from a predefined list (which may contain user-defined content) e.g. the use of faciebat in hexameter clausulae.
• specify a specific subset to run the analysis on, which may be a composite of several items e.g. all works of Vergilius + the Metamorphoses.

This task comprises at the very least:

• a front-end GUI design & implementation for the query assembler
• the back-end script that can execute the analysis and return results
• a rate limiter that puts reasonable constraints on the amount of CPU time a user can hog.

Nice-to-haves are:

• an option to schedule analysis
• an option to abort an analysis
• an option to reuse past analyses as much as possible
• an option to simulate analysis, in order to estimate cost
