configs

_settings.json - personal vscode-wide settings
settings.json - goes into .vscode dir and ignores a bunch of files so they don't show up in fuzzy search with cmd+p
tasks.json - goes into .vscode dir and adds a standard build command for elixir projects that will dump errors and warning into problem pane
