ferroelectric search misc. mongo databases

These files are included for archiving purposes. They are not intended for the general user.<br>These are compressed tgz folders generated by mongodump for multiple mongodbs used to create the ferroelectric_dataset json files. <br>These databases include the distortion databases generated from Bilbao Crystallographic Server queries, the Fireworks launchpad database (merged from multiple databases), and the full VASP calculation database (merged from multiple).<br>loadDBs.sh is included to upload the mongodumps to a mongodb after the files are untarred (tar -xvzf filename.tgz).

本批次压缩tgz格式文件夹由mongodump工具生成，对应多个MongoDB数据库，用于构建铁电数据集（ferroelectric_dataset）的JSON文件。
上述数据库涵盖三类：通过比尔巴约晶体学服务器（Bilbao Crystallographic Server）查询生成的畸变数据库、经多数据库合并得到的Fireworks发射台数据库，以及经多数据库合并的完整VASP计算数据库。
文件附带loadDBs.sh脚本，在执行解压缩命令tar -xvzf filename.tgz后，可将mongodump导出的备份数据上传至MongoDB数据库。
