Changelog:

v1.2.0 to v1.3.0 - Added functionality to value models and plotting. Some bugfixes related to ore tranches and plotting. Input header columns changed so pre-v1.3.0 input files will not work. v1.1.0 to v1.2.0 - Changed python environment requirements and package dependencies. A number of bugfixes. Significant optimisation for improved speed and memory management, providing a pathways towards high scenario regionalisation and iteration count. Addition of experimental functionality for isolated results post-processing. v1.0.2 to v1.1.0 - Added features ore tranches, development probability, production capacity uncertainty, ALL syntax for region/deposit type factor updates. Added additional input file examples for sensitivity analysis. Input header columns changed so pre-v1.1.0 input files will not work. v1.0.1 to v1.0.2 - Fixed bugs with file importation, the value prioritisation algorithm, the capacity_generate() function. Some input file column headers renamed to improve clarity, so v1.0.1 and earlier input files will no longer work. v1.0.0 to v1.0.1 - New release created to trigger establishment of a Zenodo archive. Updated version number and date.
