* initial scaffolding for benchmarks directory, including initial tachometer tests for POC

* implemented initial urql client w/ default config graphcache & execute exchanges

* troubleshooting: working with Jovi to create bypass for 'process' variable

* troubleshooting: fix for 'process' related error w/ GQL

* successfully created urql client that performs operations with execute-exchange

* refactored test queries to use async/await to get POC prior to writing read/write benchmarks

* achieved fully functional urql client

* implemented initial benchmark scaffolding for different variations of reads/writes => get feedback from Jovi to confirm accuracy of approach

* added functions to produce different entities to be used in larger read/write benchmarks

* removed Date references from newly added entities => revisit creating scalar Date later

* updated schema to reflect typing of new entities to be used in benchmark

* implemented mutation for adding writers

* added mutations for additional entities to be used for benchmarking

* implemented benchmarks for reading/writing several entities ranging from 500 to 50,000

* implemented MVP around complex query benchmark

* created complex write benchmarks

* implemented benchmarks for complex reads

* implemented mutation to update complete field on last Todo entity for benchmark

* troubleshooting: updateQuery invocation in custom updater => pushing up to get feedback from Jovi

* implemented benchmark for adding a single todo to API & graphcache

* refactored 100 entity read/write benchmarks to use async/await to handle asynchronicity

* refactored 500 entity read/write benchmarks to use async/await to handle asynchronicity

* refactored 1000 entity read/write benchmarks to use async/await to handle asynchronicity

* refactored 5000 entity read/write benchmarks to use async/await to handle asynchronicity

* refactored 10000 entity read/write benchmarks to use async/await to handle asynchronicity

* refactored 50000 entity read/write benchmarks to use async/await to handle asynchronicity

* refactored updateTodo benchmark to use async/await to handle asynchronicity

* refactored benchmarks to return data returned from queries
